Onashaft; 2a a, disc 3.1. is fixed;this-.discxhavinga long notch cut-,ina it whose ends cooperateiwithi astop-pin 3'2 arranged on the side wall; so tl'iatn themoving; of the crank: islimited to-iairacti'orr of'a turn. In addition; thetshaft z5 carries-the toothed wheel 33 =firmly fixed toit anctalsoacam 34. By means of" columns 35 a plate 3B is on the-sidewalk I situated at the-left-in-thodmw ing. Between this side wall I and the plate 36 a shaft 37 is rotatably supported, and on it a toothed wheel 38 is rotatable, which is in engagement with the toothed wheel 33. The toothed wheel 38 carries a disc 39 which, by a spring 40, is pressed laterally against a toothed wheel 4| fixed on the shaft 37, a friction disc 42 being arranged between the disc 39 and the toothed wheel 4|. The toothed wheel 4| meshes with the toothed wheel 43 which, with the toothed wheel 44, is mounted on the shaft 45. Finally, the toothed wheel 44 is in engagement with a toothed wheel 46, which is arranged on one end of a roller 41 for transporting the top sheet B.

The rod 3 is hollow and has six transverse bores which serve as guides forpins 48, whose part lying in the hollow space of the rod 3 carries a compressed spring 49. The outer ends of the pins 43 have a transverse bore; these bores serve as bearings for pins of three shafts 50, on each of which a pair of rollers Si is arranged. These rollers cooperate with the roller 41 for transporting the top sheet B and project with their periphery through windows in the plate 5.

On the shaft 45 a ratchet wheel 52 is fixed, with whose teeth three pawls 54, loaded by springs 53 and carried on a shaft 55, can be brought into mesh. The noses of the separate pawls 54 are somewhat differently displaced with respect to the teeth of the ratchet wheel 52, in order that one of these noses may certainly fall into a tooth gap of the ratchet wheel and thus lock it.

A roller 56 on a lever 57 cooperates with the cam 34, the lever 51 being swivellable about a shaft 58 against the force of a tension spring 59. The shaft 56 is rotatably supported between the plate 36 and a further plate 58 fixed to the latter. The end of the lever 57 opposite the roller 56 carries a pawl 6|, which can swing round a pin 62. A spring 63 tends to press the pawl 6| onto a nose 65 of the lever 51 by means of a pin 64 fixed to the pawl. The end 66 of the pawl 6| serves as a feeling member to contact with the markings 6! of the top sheet, of which markings more will be said later. On the pin 62 a locking disc 68 is arranged. A pin 69 fitted on the pawl 6| projects in front of a stop surface 18 of the locking disc 68, and a spring H tends to press the surface 70 on to the pin 69. The spring H is stretched between the locking disc 68 and a control part 12 on the shaft 55, the control part 12 cooperating with a pin 73 on the lever 57 and in its turn controlling the pawls 54 by means of a pin 74 arranged on it. An arm 15 of the control part 12 projects to within reach of an arm 16 of the locking disc 68.

'On a shaft 1! between the plates 36 and 60 an eccentric bush is is supported, on which a stirrup 19 can swing, whose crossbar carries a thin, sharpened tongue 89, serving as a knife.

A'rod 8!, which is suspended for swivelling on arms 82 and 82a, projects against the stirrup 19. The arm 82 is formed in one piece with an arm 83, which projects within reach of a pin 84 on the lever 51. A spring 85 tends to swivel the arms counterclockwise. The plate l4 carries an arm 86, which can swing about a pin 81 on that plate. The arm 86 projects within reach ofthe rod 8|, and a draw rod 88, which is attached to the arm 86, is connected in a manner not illustrated with the line space lever of the typewriting, calculating or bookkeeping machine.

Finally, on the lever arms 89 which can swing tween the roller 4"! and the rollers 5|.

4 about the rod 4, rollers 96 are rotatably supported, which are intended to run on the paper roller W and to press the basic sheet G onto the paper roller by means of the springs 9|.

The described appliance is attached as follows to the typewriting, calculating or bookkeeping machine, which is fitted with the plates l3 and I4.

Theside walls I are in the position indicated by the chain-dotted lines in Fig. 2. The pins I2 lie already in the slot I1 and the pins H on the latch 2|. By pressure at right-angles the latch 2| is now swivelled, after which the top sheet B is introduced between the plates 5 and 6 so that its lower edge stands up in the space be- The part 26 rests with an arm of a forked projection on the first pin 24. The pin ll then enters slot l6. The corresponding position is represented in Fig. 2 in full lines. The handcrank 29 is then pushed back into the position according to Fig.

3, whereby the appliance takes up the position shown in this figure and in Fig. 4, and the second arm of the forked projection .of the part 26 lies behind the first pin 24.

The possibility of swivelling the appliance by the guiding of the roller pins II and i2 inthe' arcuate slots I6 and H facilitates the introduction of the top sheet into the appliance, since the latter is each time for this purpose swivelled,.-

into the position shown in Fig. 2.

With the swinging of the crank 29, the toothed wheels 33, 38, 4|, 43, 44 and 46 are rotateduntil the disc 3| comes up against the stop 32. The

roller 41 thus advances the top sheet B.

The top sheet B has a characteristic mark the form of a transverse slit M (Fig. 1) made in it previously. At the beginning of the swing-1'. ing of the crank 29, the roller 56 slides off cam- 34, which is mounted on the shaft 25 rotated by The spring 59 swin'gs the lever 51, so that the pawl 6| comes to lie with the end 66 serving as a feeler member against the 1 top sheet B (Figs. 8 and 9). The end 66 then lies in the path of the characteristic mark, i. e.

the crank 29.

of the slit M in the top sheet B, and enters into it as soon as it comes to lie in front of this end 66 (Figs. 9 and 10). The upper edge of the slit M swings the pawl 6i downwards along with the In consequence of this, the arm 76 of the locking disc 68 slides away from under the I arm 15 of the control part 72 (Fig. 10). The pin 1 end 66.

1'4 frees the pawl 54, and this, under the action of the springs 53, engages with the ratchet wheel 52, which thus locks the shaft 45. The further swinging of the crank 29, then causes only a slid- 1 ing of the friction discs 42 between the disc 39 and the toothed wheel 4!; the roller 41, how-J ever, does not turn any further and the top sheet B remains standing at the position determined by the slit M. It is to be noted, that, the initial position (Fig. 8) the pin 13-through the control part l2and the pin [4 keep the pawls 54-out of engagement with the ratchet wheel.

Writing can then be done on the top sheet B,

the basic sheet G being written on simultaneously in the known manner by means of carbon paper. :1

If the line space lever of the machine is operated after writing the line, i. e. when posting is completed, the consequence is that the draw rod 88 is moved downwards in the direction of the arrow (Figs. 4 and 6) The arm 86 then swings round the pin 81 and presses with its end against:

the rod 81. This rod swings the stirrup l9 anemone:

61:, and this end 56 presses the. paper of the top.

sheet, below the cut mark 6:1, into: the depression,

so. that the upper edge of the paper can move the-end: B downwards.

Naturally the knife could be shaped in such a.

way that, in place of the cuts 61, slots of rec! tangular shape or circularperforations are made. The advantage of simple cuts. is that they can be applied in the middle of the writing without causing any" trouble or inconvenience;

To remove the appliance, from the machine, the latches 21. are swung away by means of the handle. 22,. so that the pins H and 12' can be withdrawn from the slots I6 and I1.

When swinging the crank 29 back into the initial position, one arm of the forked projection of the part 26 comes up against the front pin 24, so that the appliance is again swung into the position according to the full lines in Fig. 2, and this facilitates the introduction of the top sheet.

Along with this swinging back of the crank 29, the cam 34 swivels the lever 51. Then the pin 13, through the control part 12 and the pin 14, brings the pawls 54 out of engagement with the ratchet wheel 52, and the pin 84 keeps the rod 8| in a position in which the knife 80 is removed from the top sheet.

In order to be able to alter the distance apart of the cuts with respect to each other within certain limits, the bush 18 can be rotated round the shaft 11 and fixed to it. Since this bush is formed as an eccentric bush and the stirrup I9 is carried on it, the position of the knife is altered when the position of the bush is changed.

The plate 5 consists preferably of transparent material, in order that the entries may not be hidden.

Instead of the handle 29, a rotary knob could be mounted on the end of the shaft 25. or the shaft 25 could be coupled to an electric motor, which could be switched on for the necessary time at each requisite booking or when introducing a new top sheet.

As a characteristic marking on the top sheet, also raised stampings could be provided, which as projections would act on the end 66 of the pawl 6|.
